hi I have just bought a uk 2015 xc60 and d5 r design lux nav
ive had it around 2 weeks and like it .
just a few questions if anyone can help

how do I find out if its up to date with software versions ?
ie maps and running the car itself ?
if its not how do I go about getting it done .?
I will fit a towbar later someone mentioned it might need a software change for that ?
are there features on the car that just need unlocking to have ? I guess I will have to pay a main dealer for this if its possible .

thanks
